For powerpc*-*-*spe* in config.gcc, for powerpcspe-*-* in config.sub,
yes. Which is also why the latter is a larger change: all other
packages would see it as a separate arch, too; which might make it a
non-starter.

Yes, and vice-versa. Of course the powerpcspe port can remove a lot
more (VMX, VSX, 64-bit!)
But these are the easy parts :-)
